IMPRovEMi-:NT IN GAS APPARA'rus.

Specification forming part of Letters Patent No. 166,867, dated August17, 1875; application filed July 21, 1875.

To all whom it may camera:

Be it known that I, ADoNIs GLAcHnT, of Alexandria. in the county ofAlexandria and State of Virginia, have invented a new and usefulImprovement in Gas Apparatus; and I do hereby declare that the followingis a full and exact description of the same, reference being had to theaccompanying drawings and to the letters of reference marked thereon.

This invention relates to household apparatus for making gas; andconsists, mainly, in certain special details of construction, by meansof which certain improved results are obtained, as will be fullydescribed hereiuaftor.

In the drawings, Figure l represents a front elevation of my improvedapparatus; Fig. 2, a partial plan view; Fig. 3, a longitudinal sectionalelevation through the retort; Fig. 4, a perspective view of theret-ort-door; Fig. 5, a sectional elevation of the retort and boxdoors;and Fig. 6, a sectional elevation of part of the projecting rib of theretort, and the corresponding recess of the retort-door.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe fully its construction and manner of operation.

A represents a cooking or other household stoveror furnace, providedwith a retort, a, Fig. 3, which in this case takes the place of thefire-brick, and forms consequently the fire` back, it being so supportedas to permit the fiame to surround it upon all sides. al, Fig. 6,represents a semicircular or other curved rib projectmg from the face ofthe retort and extending about the opening; and az, a door provided witheorresponding recesses (L3 and locking-screws 0,4, by means of whichlatter it is securely fastened in place when desired, clay or otherlutin g being employed, if desired, to make a tight joint.. This door isprovided upon its sides near its lower ends with pivotpins resting inslotted arms, as shown in Fig. 4, which project from the face of theretort. By means of this construction the door is provided, as it were,with loose hinges, so that it is capable of being turned freely to openand close the retort without interfering With its adjustment by means ofthe securing-screws, when it is desired to tightly close the same.

'the receiver are delivered to the retort.

(L5 represents the discharge-pipe for the gas, i

and ae the pipe through which the contents of B represent-s a box-door,which is adapted to inclose the door of the retort, and prevent anyescape of gas into the room. The special construction of this door isrepresented in Figs. 8 and 5, in which, it will be observed, the edge ofthe door when closed projects within the line of the stove, so that anyleakage of gas is delivered into the mterior of the stove instead ofinto the room. found sufficient to cause the top plate of the door toproject within the line of the stove, in consequence of the tendency ofgas when in a hot current to rise in straight lines, rather than tospread to either side. O represents the receiver, which is designed toreceive fat or grease aocumulating from time to time, which wouldotherwise be thrown away. o represents the funnel, into which theproperlymelted fat is poured, the upper stop-cock being open. 01represents the receptacle into which the contents of the funnel flow,and from which they are discharged into the retort through the stop-cock02. 02 03 represent the cocks, by means of which the escape of gas isprevented, the upper cock being closed always before the lower cock isopened. d represen ts a joint of any suitable construction, by means ofwhich, when desired, the main pipe may be In practice it will be readilyconnected with, and disconnected from,

the discharge-pipe a5 of the retort. D represents the water-box placedupon the hot pipe between the retort and the purifying-chamber, by meansof which the gas is partially cooled. d' represents a gage, adapted toindicate the amount of pressure in the pipes.

E E represent purifying-chambers adapted to receive the gas at thebottom and discharge it at the top, which are provided with the openingse el for introducing the purifying materials, water, linie, &c., and theopenings 82 83 for drawing off the tar and residuum. F represents thegasometer having the double wall f f and vertically-moving holder fl,sustained by chains and weights in any proper manner. It is providedalso with the inletpipe f2 opening beneath the water, and thedischarge-pipe f3 having the disk-shaped cap fi extending nearly to theside of the inner wall, but leaving sufficient space for the passage ofthe gas, as shown. G represents a branch-pipe connected with theservic'e-pipes, by means of which the gas may be used as made withoutgoing through the gasometer.

Some of the adyantages of the described construction are as follows: Thegas is made either from coal, grease, or oil, by the heat of= theordinary fire made for cooking or heating purposes, so that no extraexpense is incurred for fuel. The waste fatty matter of the kitchen, bymeans of the receiver, may be readily utilized instead of being wasted.The coke and residuum in the retort may be employed for fuel after thegas has been removed. Bythe special construction of the door of theretort a tightjoint is cheaply and easily made. The auxiliary box-dooralso prevents any leakage that may occur from escaping into the room.The purifying-chambers are exceedingl y simple in their construction,and are adapted to permit readily the introduction of the purifyingmaterials and the removal of the residuum. By the employlnent of doublewalls in the gasometer the gas is much more securely held. By theemploymen't of the disk-shaped cap to the discharge-pipe the incominggas from the inlet-pipe is relieved from pressure, and conseqnently alsothe retorts, so that lthe generation ot gas is not interfered With. Bylocating the inlet-pipe beneath the Water the gas receives afinalpurification as it enters the gasometer. By the employment of the branchpipe the gas may be nsedodirect Without passing through the gasometer.

The general construction of the parts is so simple and the arrangementsso compact that the apparatus may be set up by unskilled labor in anordinary dwelling,J and be readily removed from place to place whendesired.

Having now fully desoribed my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In combination with the stove and retortdoor, the box-door, the inneredges of which project Within the line of the door for the purpose ofpreventing leakage into the room, as described.

2. The 'combination of the retort-door having pivot-pins, as described,with the slotted supporting-arms, the construction being such that thedoor is capable of i adjustment upon the supporting-arms, for thepurpose of tightly closing the retort, as described.

3. In combination with the gasometer having its supply-pipe dischargingin the lower part of the tank, the discharge-pipe 3 having thedisk-shaped cap f4, the construction being such that the gas enters atthe ed ges of the cap and passes out at its center, as described.
